SD-C combat trigger duty
Reviewed on April 27, 2026Verified with Build

Geissele SD-C is the combat tuned version of the Super Dynamic. Heavier first stage than the 3-Gun trigger to prevent accidental discharge. Break is at 4.5 lb total. Designed for duty use where light triggers arent appropriate.
